Again, the FCS papers are a good start. Best to find a library with free access. They are a bit expensive on DVD. Bob > > Thanks!!!

How about three doublers: 10 MHz -> 20 -> 40 -> 80 MHz and then divide by 5 -> 16 MHz? Jeremy N6WFO On Sat, Sep 29, 2018 at 9:17 PM Hal Murray wrote: > > > > What's a clever, simple, reliable (pick 2 of 3) way to get 16 MHz out of 10 > > MHz?

**************************** A bit late but here is my report from a quick jaunt at Harkness SP in Waterford yesterday 10/22 (the brush dump portion only).

------------------------------ Observation start time: 06:00:00 Observation end time: 15:00:00 Total observation time: 9 hours Official Counter: Dave Brown Observers: Colin Horstead, Ed Taylor, Eleanor, Jack Finney, Keith Sealy Visitors: A few more today...but not nearly as many as yesterday when we saw a total of 122 people visit

There were flocks of small birds flying over the Tower including American Pipits (36), Horned Larks (18), House Finch (14) and Eastern Bluebirds (36), four of which paid us a visit and perched on the tops of a nearby tree. Purple Finch (3) and Pine Siskin (3) were also spotted. Noticeable numbers of American Goldfinch (410) also flew by.

After many yeaqrs admiring form afar, I've acquired my first piece of timenuttery, an Efratom PC-10 portable rubidium clock, S/N 101 (possibly the first production unit?).
